To all whom it may concern:

thereon, which form a part of this specification.

The drawing shows a side view in section of my invention.

The object of my invention is to produce certain improvements inbill-holders and per per-files, whereby a much cheaper-and strongerdevice isobtained than in those in common use. The improvement is simpleand may be thus described.

In the accompanying drawing, ashows the bottom or base of the file. bshows the back, which is attached to the bottom and curved, asillustrated in the drawing. 'cis a spring, bent to conform with-thecurve of the back, and is fastened at one end to thebottom a,and' at theother to the inside of the inner part of Rigidly attached to the spring,and extending the length of the back of the file, is the holder orretainer d. This holder is formed of a single piece of metal doubled atits'lower edge over a strip of as to hold it firmly clasped or clampedbetween the two parts ofthe holder which form the any suitable manner,the outer end ,of the strip of leather 0, which is heldat its oppositeend between the two parts or double of the retainer. Between the base aand the retainer d are placed suitable index-sheets for the filing ofletters, bills, 850.

The operation of the spring will keep the holder pressed firmly downupon the papers within the file, and when it is desired to introducemore papers all that is necessary to do is to turn the cover over uponthe back b, and press down on said cover, which-operation will raise theholder from the papers within the file, and allow of the insertion ofsuch others as may be desired. Any number of springs may be employed,two, however, being preferable, one

retainer, and its manner of attachment to the cover; but

\Vhat I do claim as my invention, and desire to secure by LettersPatent, is
